Answer:  f(t) is shifted 20 units to the left and 7 units down

Step-by-step explanation:

The general form of a sin function is: y = A sin (Bx - C) + D

y = sin (5t)

f(t) = sin (5t + 20) -7

Answer:

 1           1

------ + -------    

r^7      s^12

Step-by-step explanation:

r^(-7) + s^(-12) can be re-written as

 1           1

------ + -------    by putting to use the rule:

r^7      s^12

                1

x^(-a) = ----------

              x^a

For this case, we must simplify the following expression:

[tex]r ^ {- 7} + s ^ {- 12}[/tex]

By definition of power properties we have to:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

So, rewriting the expression we have:

[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]

Answer:

[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]

Answer:

776.46 m

Step-by-step explanation:

According to the scenario it is a question of right angle triangle

To find the height of the plane above the ground we will use trigonometry identity.

here Ф = 15°

        opposite = height

        hypotenuse = 3000m

Plug values in the formula above

height = sin(15)(3000)

           = 776 .46 m

(make sure your calculator is in degree mode)

Answer:

776.46 m

Step-by-step explanation:

The angle of elevation is 15 degrees which is measured from the horizontal.

The height above the ground is the opposite side of the triangle, the hypotenuse is the 3000 m and the angle of elevation is 15 degrees.

The sine ratio is the one one that ties the relationship;

Therefore;

sin 15 = x/3000

x = sin 15 × 3000

   = 776.46 m

"The number c is a​ zero the polynomial function y=​P(x) if and only if x-c is a​ factor of the polynomial​ P(x)."

Step-by-step explanation:

We have been given some statements with blank spaces:

"The number c is a​ _______ of the polynomial function y=​P(x) if and only if x-c is a​ _______ of the polynomial​ P(x)."

Now we need to fill those blank spaces by suitable words.

We know that if x=5 is some root (zero or solution) of the polynomial function then (x-5) works as factor.

So using that logic, we can fill the blanks spaces as:

"The number c is a​ zero the polynomial function y=​P(x) if and only if x-c is a​ factor of the polynomial​ P(x)."

Answer:

 I am 86% sure that it is The number c is zero the polynomial function y=​P(x) if and only if x-c is a​ factor of the polynomial​ P(x)

I believe it is because it would be he most simplistic answer to be honest because for example 10,8 it is the same as 5,4 so u would put 5,4 because it is simplified so put (2.1,0) as your answer

The ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).

Here's my reasoning:

- The graph intersects the x-axis at (2.1, 0): This means that any point on the x-axis, including (2.1, 0), has a y-value of 0. However, this doesn't guarantee that (2.1, 0) is a solution to the equation itself.

- The graph passes through the point (-2.5, 3): This means that the equation of the graph must yield a y-value of 3 when x = -2.5. Therefore, (-2.5, 3) is a solution to the equation.

The other points are not on the graph itself:

- (0, 0.6) is above the x-axis but not on the graph's line.

- (-1, 1.8) is also above the x-axis but not on the graph's line.

Therefore, the only ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).

Final answer:

The property illustrated in the equation is the Commutative Property of Addition. It states that the order in which numbers are added does not affect the sum.

Explanation:

The equation showcases the Commutative Property of Addition. This property asserts that altering the order of addends doesn't impact the sum. Specifically, the given equation, 6 + 4 + 3, demonstrates this property as it equals 6 + 3 + 4. In essence, rearranging the sequence of addends doesn't alter the total, underscoring the flexibility of addition. This fundamental property simplifies mathematical operations, allowing for easier manipulation and calculation of sums, regardless of the order in which numbers are combined.

The Commutative Property of Addition plays a pivotal role in arithmetic, streamlining calculations and enhancing mathematical efficiency.

Answer:

$5093.37

Step-by-step explanation:

To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.

Previous balance = $398.64

Purchases = $1,257.99

Payment = $250

Credit Line = $6,500

Now first we add together her purchases and previous balance.

398.64 + 1,257.99

This will give us:

$1,656.63 Total deductions.

Now we subtract that to her credit line.

$6500.00 - $1656.63

$4843.37

Now we take her payment and add it to her credit line.

$4843.37 + $250

$5093.37

So Rebecca's available credit is $5093.37.

The terms of an arithmetic sequence are generated by adding a fixed term [tex]r[/tex] every time.

So, we start with [tex]a_1=15[/tex], and we continue with [tex]a_2=15+r[/tex], [tex]a_3=15+2r[/tex] and so on.

As you can see, the general rule is [tex]a_n = 15+(n-1)r[/tex]

With this information, we can derive [tex]r[/tex], knowing that

[tex]a_{100} = 307 = 15+99r \iff 99r = 292 \iff r = \dfrac{292}{99}[/tex]

So, the sum of the first 100 terms is

[tex][tex]\displaystyle \sum_{i=0}^{99} 15+i\dfrac{292}{99} = \displaystyle \sum_{i=0}^{99} 15 + \displaystyle \dfrac{292}{99}\sum_{i=0}^{99} i = (15\cdot 99) + \dfrac{292}{99}\dfrac{99\cdot 100}{2} = 1485 + \dfrac{490342}{99}[/tex]

Answer:

Faster plane --> 600km/hr

Slower Plane --> 500km/hr

Just use the graph to follow each translation until you get thee right answer, or you can count how many spaces are from the pre-image to the image. Just make sure to always use the same point.

The transformation from figure A to figure A' are:

Translating 6 units to the right.

Translated 9 units up.

Option B is the correct answer.

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

We will take two coordinates from the figure.

Figure A has the coordinates:

(-5, -2) and (-4, -2)

And,

Figure A' has the coordinates:

(1, 7) and (2, 7)

Now,

Translating 6 units to the right.

(-5, -2) = (-5 + 6, -2) = (1, -2)

And,

(-4, -2) = (-4 + 6, -2) = (2, -2) _____(1)

Again,

Translated 9 units up.

(1, -2) = (1, -2 + 9) = (1, 7)

And,

(2, -2) = (2, -2 + 9) = (2, 7) ______(2)

From (1) and (2) we see that,

Figure A to Figure A'.

Translating 6 units to the right.

Translated 9 units up.

Thus,

The transformation from figure A to figure A' are:

Translating 6 units to the right.

Translated 9 units up.
